Description

Perfluoro-1,3,5-Trimethylcyclohexane is a fully fluorinated, highly volatile cyclic hydrocarbon with exceptional chemical and thermal stability. This compound is valued for its unique combination of low surface tension, high density, and excellent dielectric properties, making it a critical functional fluid in advanced manufacturing. It is primarily sought by industries involved in electronics, aerospace, and specialized chemical synthesis where inert, high-performance materials are required.

Application

• Electronics Manufacturing: Used as a heat transfer fluid or dielectric coolant in high-performance computing and semiconductor testing equipment.
• Aerospace & Defense: Serves as a functional fluid in inertial guidance systems, gyroscopes, and other precision instruments requiring stable, dense, and inert media.
• Chemical Vapor Deposition (CVD): Acts as a precursor or carrier gas in the deposition of fluorinated thin films for hydrophobic coatings.
• Specialty Solvent: Employed as an inert, non-polar solvent for sensitive reactions or extraction processes where traditional solvents are reactive.
• Calibration & Testing: Utilized as a standard or reference fluid in analytical instrumentation, including gas chromatography and mass spectrometry, due to its well-defined properties.
• Acoustic Testing: Functions as an immersion fluid in ultrasonic testing and calibration due to its consistent acoustic velocity and clarity.

Quality Control

Our Perfluoro-1,3,5-Trimethylcyclohexane is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, assay, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing purity (typically >99% by GC), specific gravity, boiling point, and other key parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 15-25°C.
